the charred illager

The charred illager is a undead illager boss mob that can only be summoned with a summoning table infront of lava in the nether. the summoning table is crafted with 3 netherack at the bottom, a eye of ender in the middle, 2 pieces of Blackstone next to the eye of ender, a piece of netherite at the top, and two gold next to the netherite. once you put two diamonds and a totem of undying, the summoning begins. he rises out of the lava, and he starts out transparent, then goes not transparent, and floats to the table and stands on it. he has a netherite sword, is immune to all fire and lava, has 150 hit points, a dark blue boss bar, and deals 4.5 hearts of damage. he likes cold biomes, snow golems, other illagers, and water. all illagers that are near by him will come to his aid, and he hates all fire mobs (blaze, magma cubes, etc..) and he hates it when the player lights other mobs on fire. upon death, he evaporates, and he drops a dark blue amulet that takes up your off hand, has 300 uses, and reduces the amount of damage dealt to you by all non boss mobs. the acheviement for summoning him is "he lives again" and the one for killing him is "he's still alive" implying he's still alive.
